My cycle with live rock is coming to an end. Nitrites were about 0.25-0.50 this am. My question is, should I add a few snails first (no hermits) or add 2 clownfish first? I have a 55 gallon with sump. I have a moderate diatom bloom. Mostly on my live rock (8 lbs) and a light dust on my dry rock (50 lbs) and a thin layer on the sand. Not on my glass but trace amount on my overflow column. I dont want a large Cuc because I dont want them to e hungry. Also will adding a Cuc cause a mini cycle?

It really won't matter once your tank is cycled. Adding a cuc won't cause a mini cycle if you're fully cycled already. Their bioload is very minimal. If you want you can add both the cuc and fish at the same time. The cuc will eat whatever leftovers are available.

I still believe that fish should be first. This is just over my thoughts on their purpose, to clean up. If there isn't anything to clean up then why have them? And I don't see the point of feeding just so a cuc can survive.

I thought the same thing but census seems to be to add cuc first. Do I have to feed them ya think? Dunno If it's gonna happen tomorrow cuz with my pwc my nitrates are still 40 ppm so I'm assuming that's too high correct?
